Fulton County has lost another department head. Atlanta-Fulton libraries Director John Szabo is leaving for Los Angeles, where he'll oversee one of the largest library systems in the world, serving four million people with a $113 million budget. Mayor Antonio Villaraigosa appointed him city librarian on Thursday.

Szabo has been Atlanta-Fulton's director since 2005. He's leaving in the midst of a $275 million construction program, which will build eight new libraries, fund part of the cost of a new Central Library and touch every existing branch through consolidations, expansions and renovations.
